Notification with time schedule

Need Help With My Project
1

I have tried many times but the results are not as good as my expectations. I want to display a notification only once according to the time I have programmed.
I can only bring up notifications at 9 am but at other hours the notification doesn’t appear. I have tried almost the same programmers in this community, but I always fail.
maybe friends can help me in solving my problem.

thank you

void notification() {
  DateTime now = rtc.now();
 if ( now.hour() == 8 && now.minute() == 0 && sm <= 30 && !notified ) {
   notified = true;
   Blynk.notify ("watering is done"); 
 }else if ( now.hour() == 8 && now.minute() == 0 && sm > 30) {
    notified = false; 
 }

 else if ( now.hour() == 10 && now.minute() == 0 && sm <= 30 && !notified ) {
 notified = true;
 Blynk.notify ("watering is done"); 
 }else if ( now.hour() == 10 && now.minute() == 0 && sm > 30) {
 notified = false;  
 }
}

You could do 1 of 2 things. Have a notify variable for first water and a notify1 for the second one. Or you could set a time out timer for just over a minute the reset the notify variable to 0.

Also add the notify check on the other two statements.
